Ignoring case-sensitivity for the moment, handling characters with accents is complex because Unicode allows visually identical characters to have different encoding. This helps ensure that files and folders with confusable names are not allowed side by side.Р”Р„lthough there is a case-sensitive variant of HFS+ which allows the co-existence of ThisFile.text and thisfile.text in the same folder, and that has been used for iOS devices, those who have tried using it on their Macs have found that many apps break as a result, as they assume that the file system is case-insensitive.

It also looked as if it might come with some major issues, particularly for those who name folders and files using characters outside the old ASCII character set РІР‚вЂњ using accents and non-Roman scripts.Р”Р„t present, in HFS+, the file system blocks us from having two files in the same folder whose names differ in capitalisation (HFS+ is case-insensitive), and whose names differ in the encoding of many Unicode characters such as those with accents (HFS+ is normalising). Designed to deliver much improved performance over the very old Apple Extended File System (HFS+) which remains standard in Sierra and earlier, it brings many other major advantages, such as snapshots and built-in support for encryption. MacOS High Sierra brings with it a new file system, APFS.
